macos - Routing low-latency audio from one CoreAudio ...
https://stackoverflow.com/questions/60292188/routing-low-latency-audio-from-one-coreaudio-device-to-another
In the world of Core Audio there is a VarispeedNode, which allows you to do basically the same thing. Big disadvantage of the async-src solution is the latency it introduces, however maybe you could specify "low-latency". In your case the synchronisation of the different audio devices will be the biggest challenge.
Big Sur Core Audio Latency Is Much Higher… - Apple Community
https://discussions.apple.com/thread/252764088
It is almost like Big Sur is enforcing a certain RTL on core audio drivers, as decreasing the sample buffer below a certain level has little to no effect on the actual latency. Testing a UAD Arrow on the M1 Air, which is a bus powered thunderbolt interface and has dedicated drivers, at 48KHz and 32 samples is giving a RTL of 3.3ms on the M1 Air ...

A "pro audio" or RTC application might need direct access to the low-level features of the Core Audio APIs to achieve minimum latency by obtaining exclusive access to audio hardware. A third-party audio API might require direct access to the Core Audio APIs to implement a set of features that might not be entirely supported by any single high ...
What Is Core Audio? - Apple Developer
https://developer.apple.com/library/archive/documentation/MusicAudio/Conceptual/CoreAudioOverview/WhatisCoreAudio/WhatisCoreAudio.html
Core Audio is tightly integrated into iOS and OS X for high performance and low latency. In OS X, the majority of Core Audio services are layered on top of the Hardware Abstraction Layer (HAL) as shown in Figure 1-1. Audio signals pass to and from hardware through the HAL. You can access the HAL using Audio Hardware Services in the Core Audio ...

Core Audio Latency - Avid Pro Audio Community

Core Audio Latency Pro Tools 12. Drew. Thanks for the great answer. It seems that the HW Buffer setting in Audio Midi actually adds to the Buffer set in Logic, so If they are both set to 256 the actual latency is 512.

That involved changing the FrameSize from 2.5ms down to 1ms. If you search for FrameSize you will find a discussion.

Yes, once you update your OS, the CoreAudio drivers get updated as well. But I wouldn't place my bet on that using the latest available OS (which means lates drivers) will improve your situation dramatically. The USB audio latency has a lot to do with the available USB bandwidth, CPU usage, free RAM - to name just a few.

I am not sure how CoreAudio safety buffer affects latency that Reaper reports, but reported latency, at 64 samples in Windows says: In = 1.8ms Out = 2.2ms While in OS-X the reported latencies are: In = 2.0ms Out = 1.9ms
